The heat treatment process is carried out in order to change the microstructure of metal materials by heating the material for a certain period of time. In the heat treatment process, a tool is needed to heat the material that will be changed in physical properties. The tool needed is an electric furnace which is an equipment that has a combustion chamber where heating is carried out in the workpiece. Generally, the use of electric furnaces is also very necessary in several places, one of which is a laboratory where it is used as an infrastructure in applying knowledge related to mechanical engineering. The laboratory is the Basic Laboratory of Mechanical Engineering at the Faculty of Engineering, Tanjungpura University. In this study, the design and manufacture of electric furnaces using A1 canteen wire was carried out. Based on the results of calculations and analysis, an electric furnace with outer dimensions of 300 x 400 x 400 mm and an inner diameter of 180 x 180 mm was obtained. Based on the results of operation and testing of the electric furnace, the highest temperature that can be reached by the electric furnace is 700 °C, while to reach that temperature it takes 50 minutes. When operating, the electric furnace uses 2,404.6 watts of electrical power and 4.9 kWh of electrical energy consumption. Tests that have been carried out at this temperature are proven to be able to melt aluminum materials with a melting point of 600 ° C.
